HEEL-NAILING MACHINE.

SPECIFICATION forming part of Letters Patent LID/110,194, datedSeptember 3, 1889."

Application iiled April 16, 1837. $erial No. 234,986- iNo model) 1 Toall whom it may concern.-

Be it known that I, FREEBORN F. RAYMOND,

2d, of Newton, in the county of Middlesex and State of Massachusetts, acitizen of the United States, have invented a new and useful Improvementin Heel-Nailing Machines, of which the following is a full, clear, andexact description, reference being had to the accompanying drawings,forming a part of this specification, in explaining its nature.

The invention is an improvement upon that described in Patent No.287,472, dated October 30, 1883, and it relates especially to a head,block, or support adapted to be oscillated or reciprocated automaticallyto bring into operative posit-ion in successive order a block carrying agang or group of awls, another block carrying a gang or group ofdrivers, and another block carrying a heel spanker or leveler, or anytwo of these devices.

It also relates to various features of construction and organization.

I have represented the invention as applied to a machine having many ofthe'features of. the National Heel-Nailing Machine, and I have shown itembodied in a number of different forms, all of which contain the sameessential elements.

Referring to the drawings, Figure 1 is a in front elevation of thecentral and upper parts of such machine, a portion of the crosspieceforming or providing a guide being broken out to show a portion-of theguidingrecess. Fig. 3 is a view in rear elevation of the parts of themachine shown in Figs. 1 and 2. Fig. 4 is a plan view thereof. Fig. 5 isa view in rear elevation of the central and upper parts of a machine,representing my invention as applied in a somewhat different form fromthat represented in Figs. 1 to 4, inclusive. Fig. 6 is a plan view ofthe form represented in Fig. 5. Fig. 7 is a vertical section upon theline w .90 of Fig. 5. Fig. 8 is a detail view to illustrate thecentering mechanism employed with the construction shown in Figs. 5, 6,and 7. Fig. 9 is a view in plan, and Fig. 10 in section, of anotherembodiment of the invention. Fig. 11 is a view in front elevation. torepresent the application to a rocated or moved therewith.

heel-nailing machine of another form of the invention. Fig. 12 is asectionnpon and in planbelow the dotted line 'y 'y of Fig.1l. Fig; 13 isa view in perspective of a part of the reciprocating head and of themovable block supporting the block carrying the drivers, to illustratethe manner of connect- -ing said block with the head. Fig. 1 1 is a Viewin vertical section of a complete nailing-machine having the form of myinvention shown in Figs. 11, 12, and 13. Fig. 15 is a I by a horizontalpivot or shaft D, as represented in Figs. 1 to 6, inclusive, or by avertical pivot or, shaft D as represented in Figs. 9 and 10. This heador support D has the block cl, carrying a gang or group of awls 01';also the block (1 carrying a gang or group of drivers (i and the blockd, the surface of which forms a heel-spanker, and which may havetop-lift-grasping devices attached to it. The head or support D isoscillated or reciprocated intermittinglyin one direction to move theawls, drivers, and spanker successively into operative posit-ion, and inthe other direction its movement is continuous and brings the awls,drivers, and spanker into place to be again intermittingly advanced.This intermittent advancing and continuous return movement, oscillation,or reciprocation is provided by a cam E, having the cam-groove e. Thiscam is represented in all the figures, excepting Figs. 11, 12, and 14,as secured or mounted upon the-cross-head A, to be recip- In Figs. 1, 2,3, 4, 9, and 10 the cam E is represented as mounted upon the verticalshaft 6'. In Figs. 5, 6, and 7 the cam is represented as mounted uponthe horizontal shaft E, which has bearings in the cross-head A and isconnected with the shaft 6" by means of the bevel-gear E and E In Figs.1, 2, 3,4, 9, and 10 the cam is represented as connected with the shaftof the head D by means of a slide-bar 6 which has a cam-pin e enteringthe cam-groove e, has

suitable bearings in the brackets or arms ex.-

tending horizontally from the head A, and is connected with the saidhead-shaft by means of the link e and arm ciwhich extends from thehead-shaft and is rigidly fastened thereto. In Figs. 5,6, and 7 themovement of the cam is communicated to the shaft of the head D by meansof a rack-bar c, which has a cam-pin 6 entering the cam-groove e of thecam E. This rackbar is in every essential respect like the slide 6 andinstead of being joined to the shaft of the head D by a link it isconnected therewith by means of the rack-teeth e and thesegment-gear'e", which is fastened rigidly to the shaft. Thedriving-shaft c is connected with the shaft F by means of thebevel-gears ff. As the cross-head A and cam E, in every form ofconstruction except that shown in Figs. 11, 12, and 14, is movedvertically, the connections between the end of this shaft and the cam E,as in Fig. l, or the bevel-gear, as in Fig. 6, is provided by making thecam or bevel gear. movable upon the shaft 6, and connecting themtherewith by means of a fast feather, so that they may be continuouslyrotated. In Figs. 11, 12, and 14 the cam E is not attached directly tothe cross-head A, but to the cross-plate G below it. It is operated,however, by the shaft 6, and it is connected with a slide-plate g, whichis adapted to be moved upon the plate G forward intermittingly, topresent the awl-holding block, the driver-holding block, and thespanker-block, successively, to the arm g on the reciprocating head.This slide-plate g is secured to the plate G by means. of the. caps g(see Fig..l1,) and the plate is connected with the cam E by means of thebent lever g which is pivoted at 9 when one arm of which is connectedwith the plate g and the other with the slideplate 9 which has a cam-ping entering the groove 6 in the cam E. Each of the blocks d d d issupported by a separate block the block (Z by the block f, the block 01*by the block f, and the block (I by the block f These blocks f f f eachhave a dovetail f which fits the dovetail recess f uponthe cross-plateG, and also the dovetail f upon the reciprocating arm g, so that uponthe movement of the slide-plate g they are moved into the groove f ofthe plate G successively into the groove f of the arm g. The surface ofthe arm 9 preferably should be made somewhat smaller than the surface ofeach of the blocks, and when this form of construction is employed Iprefer to use the guides f, extending upward from the table carrying thetemplet, which preferably are inclined somewhat at their upper ends, andwhich are adapted to receive each of the blocks ff f as they aresuccessively moved downward and guide them during their verticalmovement. These guides must be of a length sufficient to receive theblocks before the awls or drivers enter the holes in the templet andnail-carrier, respectively. The

cam E provides these blocks with an intermittent forward movement tobring them successively beneath the plunger or arm g and a continuousbackward movement. WVhen the awls, drivers, and spanker are thus movedupon the stationary supporting-plate into position beneath areciprocating plunger, it is necessary that the plunger be given aninterval of rest at the time the cam E operates to move the blockssuccessively into position, and this is accomplished by operating thecross-head A by means of a cam-groove M in the cam-disk m on the shaftm, the said camgroove being connected by means of the lever m pivoted atm with the toggle m. The upper link m of this toggle is pivoted at m tothe bed of the machine, and the lower link m at its lower end to thelower movable cross-head m which is connected by means of the rods mwith the upper head A. Each rotation of this cam-disk M reciprocates thehead A, and also provides it with a period of rest at the end of itsupward movement. 'The cam M may be connected directly with the lowercross head m or with the rods m, if desired, instead of through theconnectinglever and toggle described.

- In operation the bootor shoe is placed upon the last, the heel placedin position, and the machine is set in operation. The stop-m0- tion maybe so arranged as to stop it at the end of each reciprocation of thecross-head A, or to provide it with two, three, or more continuousreciprocations and then stop it. The cam E is so timed that upon thefirst reciprocation thegangof awls is brought into position to bereciprocated immediately before or upon the downward movement of thehead A, and is moved out of position by said cam upon the upwardmovement of the head A, and at the same time the gang of drivers isbrought into position, and upon the next reciprocation of the head, thenails having been fed to the holes which were formed by the awls in theheel-blank, they are driven into the heel-blank. and soles of the bootor shoe and are withdrawn and moved out of operative position by the camE during the upward movement orat the end of the upward movement of thecross-head A, the

.manner of automatically moving the awls, drivers, and spanker, or anytwo of them, into operative position may .be used with anyheel-compressing mechanism.

Having thus fully described my invention,
